mii_eee_cap...nkmode_sup_t(9)

💖 mii_eee_cap...nkmode_sup_t(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a function page, and the name lowkey got chopped in the header (mii_eee_cap...nkmode_sup_t(9)) but don't panic, it's still the same iconic little helper 🎀

✨ SYNOPSIS ✨

void mii_eee_cap2_mod_linkmode_sup_t (unsigned long *adv , u32 val );

🦋 ARGUMENTS 🦋

• adv — this is your target, the linkmode settings you're writing into. it's the destination, the main character, the one getting the glow-up 💅
• val — the register value. just a plain u32, sitting there, full of secrets 🍓

🌸 DESCRIPTION 🌸

so like, what does this actually do? it's a function that translates the value of the following registers into the linkmode, bestie. and the register in question is:

• IEEE 802.3-2022 45.2.3.11 "EEE control and capability 2" register (3.21) 👑

that's it, that's the whole vibe. it takes the register value and translates it over to linkmode land. no cap 🫶
